The state Medical Examining Board on Tuesday disciplined two physicians with fines of $10,000 or more, including a Stamford doctor for a lack of documentation while prescribing to employees. The board also agreed to withdraw charges against two other physicians who either voluntarily relinquished their medical license or agreed to allow their license to lapse. Dr. Laurence Kirwan of Stamford, was fined $12,500 for a lack of adequate documentation while prescribing medication to three of his employees who were also patients from 2009 to 2017, according to a consent order. It was Kirwan’s second reprimand and fine before the board, according to state records. In 2017, he was fined $2,500 for failing to maintain adequate treatment records and documentation for a surgical patient from March to July 2014.
